Application filed February 20, 1920. Serial No. 360,225.

ToaZZ'wlwm itmay concerm Be it known that I, AUR LIo BARGHIESI a subject of King of Italy, and resident 0t Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in an Automatic Valve-Closer, of which the following is a specification.

This invention relates to an automatic valve closer, and has for its object the pro duction of a device, wherebythe flow of gas in a gas conduit is automatically turned oif, in case the light of any gastip and the like that is fed guished without shutting it ofi by its regular gas cook. V.

The organization of the invention primarily comprises; a valve which shuts off the flow of gas in the conduit and which valve is caused to be seated on its seat by the, expansive effect of' springs or mechanism that will cause the valve to move.

Figure 1 is a partial section as on the line 1, 1, of Fig. 3; Fig. 2 is a right hand 2,2; Fig. 3 is a top plan view of Fig. 2; Fig. 4 is alright hand'side view of some of the elements shownin Fig. 1; Fig. 5, shows.

a section of Fig. 4 on the line 5, 5; F ig, 6 shows a partial section of Fig. 5 -on-the line 6, 6; Fig. 7 represents a section on the line 7, 7 of Fig. 5; Fig. 8 is a section on theline. 8, 8 of Fig. 9-and Fig. Qshows a section on the line 9, 9 of Fig. 8.'

The automatic valve. closer has its top and bottom ends connectedto the gas conduit 20. A valve chamber21 of the closer is threaded at 22 for one endof the conduit 20.

A conduit and controlling support designated in. its entiretyby the letter A, comprises exteriorly threaded head23 and the 'exteriorly threaded base 24.. The head 23 has formed therein the fourports 25, the

guideopening 26 and the valve seat 27. The base 24 has formedtherein the ports30 in line with the ports 25jand the guide opening 31, which latteris in line with the guide opening 26. A lug 32 extends from the base 24 to lengthen the guide opening 31. Gas conduits 33 connectthe ports 25 and 30. A valve 34 has extending therefrom the Valve stem 35, and. the latter carries thelifting pin 36.1 A guide recess 37 is. formed speciflcatlon' of Letters Patent. 7 Patented 'by the conduit is extin-' side view and-section of Fig. 1 on the line spur gear 62. the rack 69.

in the valve stem 38 located in said thereof fastened therein.

A stop orlocking opening 39 is formed sept. 27, 1 921.

and a Hat leaf spring recess 37 has one end in the' valve stem below the guide recess 7 37 and a trip notch 40 is formed in said stem below the opening 39 and is on the side opposite the guide recess. 37; A supporting guide bracket is fastened to the base 24 and has formed in its upper-end the dovetailed guide 46 Arack 47 with the dovetailed base 48 is slidably supported in the dove-tailed guide 46.. A'toe 49 is formed with the base 48 and registers'with the guide recess 37 A sheet 5 0 of non-'heatcond-ucting material bears against 'a' couple of the condu1ts 33, and a plate bracket 51 bears against said sheet. Flanges 52 and lugs 53 are formed with the plate bracket 51. Screws 54' secure the flanges 52 to the head 23 and to the base 24. A

Journal lugs 55 and 56 are formed with the plate bracket 51. In the journal lug 55 is journaled a spindle 57 which has fastened thereto the spur gear 62 rack 47. A

1 b 1 gear segment 64 is pivoted to p ate rac et 51 on thepivot 65. The-teeth of gear segment'64 mesh with the spur gear I 67 is secured to the base 24'and has I and larger, spur. gear 63. The spur gear '62 meshesjwith the i'sslidably supported in the dovetailed guide 1 68... A toe 71v is formed with the base 70 which can register with the trip notch 40 of'the valve stem 35. I the journal lug 56 is journaled a spind1e'75 which has fastened thereto the spur gear 76 and the smaller spur gear 77. The latter is of the samediameter asthe spur gear 63,'andthe spur; gear 76 islarger in diameter than the The spur gear 76 meshes with teeth of thejsegment 78 mesh with the spur gear 77 and its pitch radius equals the pitch radius of the segment 64. The other end of the gear segment 78 carries a pin 80. vA spring supporting plate 85 is fastened to the lugs 53 by means of the 'screw's86." A heating channel is formed with the plate 85 p A gear segment 78 is pivoted tofthej plate bracket51 on the pivot 7 9., The,

and comprises the vertical member 87 and j ing 96.

A spiral spring 100 has one end inserted in the slots 92 of the sleeve 90'anda spiral spring 101 has one end inserted in the slots 92 of the sleeve 91. The other end of the spring 100 extends through the openin 95 conduit 20.

andhas formed therewith aneye 102. he other end ofthe spring 101 extends through the opening 96 and has formed therewith an eye 108. The eye 102 is engaged by the pin 66 and the eye 108 is engaged by the pin 80.

Aogas chamber B has formed therewith thethreaded shank 110 which is in threaded engagement with the lower portion of the The chamber 13 has extending therefrom the gas channel 111 which terminates in the cup 112 having theair openings 118. A gas 'tip 1141 is threaded in the cup 112 and registers with the channel 111.

A glass sleeve 115 is supported in the cup 112 and supports the cap 116. A cover 117 with the air openings 118 is hinged to the cap 116. Slots 119 and-120 are respectively formed, '11 the glass sleeve 115and in the cap 116 to permit the insertionof thewall of the channel 88 and the cap 89. A hinged cover 7 is shown with themembers 125 and 126 connected at one pair otedgesby the hinges 127 while at their other ends are formed flanges 128 and 129 connected by the bolt 180. The said cover has extending from its inner surface a pivot bracket 181 in whichis supported the pivot 182. 'Alitting leveris 'shownwith. the arms'188 and1'184. The arm 183 coacts withthe lifting pin 86 and to the arm 1841 is fastened'the valve littingchain 185.

A spring 186 bears between the inner surface of the member 126 of thehinged cover and arm 188. The said hinged cover encircle's the support A. An opening, 187 is formed in the member 126 for the arm 184,

.To operate the automatic valve, closer it maybe first considered that thevalve 8a is in its. closed position as indicatedin. the drawingsQ To use the valve closer the operator pulls the lifting chain 185 I which causes the arm 18 8 of the lifting lever toengage the lifting pin 86. By this meansthe valve ti l with its stem 85 are lifted to their Y raised. or upper position, until'the toe 419. of

the dovetailed base 48 looks withjthe stop or loclnng opening 89 which looks the valve 34 in its ralsed position. Before the valve 84;

Both ot the sleeves B' to the tip expands both the springs is raised, the toe the segment 64: turns the spur gear 68 and thereby the spur gear 62 causes the rack 47 gas will now flow through the as conduit 20 in the direction of the arrow by way; of the gas conduits 88 and from the chamber 114. The'operator next lights the gas at the flows through the channels 88 and 87 and into the casings 92 and 98; The heated air 100 and 101.. When the spiringllll expands it causes the rack 69 49 bears against the spring 28, by virtue ofthe tensionot the spring 100. When the toe #19 is opposite the opening 89,

to niovelthe toe 49 into the opening 89. The r tip 114, whereby heated air tomove inwardly toward the stem and thereby the toe 71 looks with the trip 40;and holds the' st'em 85 with its'valve 84 inits raised position. The spring -also e'npands and causes thetoe 49 to disengage from the stop opening 89, and which occurs after the toe 7 1 is engaged with the notch 40, because the spur gear 76 is largerin diameter than the spur gear 62. The gas flows now in the regular Way through the automatic valve closer.

notch In case the flow of the gas is interrupted;

the lightfrQm the tip 11 1 will be extinguished andthe springs 100,101, will cool and contract. Under these conditions the valve 3 1' should close and the flow of gas shouldjbe interrupted. This is accomplished virtue of the toe 71 first disengaging from the stop notchO. The larger gear 76 operates the rack 69 in a shorter interval of time than the small gear 62 operates the rack 16. Thestem 35 with its valve 3 1 will now drop toits closed position and shortly thereafter the rack e7 -moves inwardly and the toe 4:9 bears against the leaf spring 88.
